I received my Ph.D. in experimental condensed matter physics in 2011 from Washington University in St. Louis working with Professor James Schilling. My thesis research was focused on studies of magnetism and superconductivity at extreme pressures.

Right after my Ph.D. I moved to the Advanced Photon Source (APS) at Argonne National Laboratory (ANL), with a joint appointment from COMPRES (Consortium for Materials Properties Research in Earth Sciences) and the APS. At the APS I worked first as a postdoctoral research associate and later as a beamline scientist, mostly working at nuclear resonant scattering beamlines in the Inelastic X-ray and Nuclear Resonant Scattering (IXN) group. I joined the Department of Physics at UAB in August 2019.

Research Interests

I use high pressure as a tuning knob to study the fascinating phenomena (superconductivity, magnetism, valence and crystal structural transitions) in strongly correlated systems. In particular I am interested in understanding the interplay/competition of magnetism, superconductivity, and lattice dynamics on a microscopic scale. I investigate pressure and temperature driven transitions using lab-based transport and magnetization methods and state-of-the-art synchrotron spectroscopy techniques (synchrotron Mössbauer spectroscopy, nuclear resonant inelastic x-ray scattering, x-ray absorption, x-ray emission etc.).
